That's the thing, though. The Fallout series was never focused on being an extreme sandbox series like the TES games are. Bethesda tried to force it to be an extreme sandbox RPG. They succeeded in the sandbox aspect, but I felt they somewhat failed at the RPG aspect. I didn't feel like the player had any real effect on anything. I don't feel like Obsidian failed on the exploration front so much as they didn't place as much importance in it as other aspects of the game, and Bethesda (seemingly) placed heavy importance on it while neglecting other aspects of the game.
Just my opinion. I think different people just look for different things in their games.
There are two ways to look at this. Are you playing the Map, or are you playing the Game. If you are playing the map, it is lacking. However the map serves the game of Fallout New Vegas just fine.
Would it be better if the map on the Pip Boy was only as big as the areas that have content in them? Or they spread things out some more? Maybe there are future plans for those areas, maybe not. Could more have been put in there, sure, but would it serve the Game? I am playing Fallout New Vegas, not the map. I think some folks issues are First Person Shooter maps are getting huge and there are loads of places to make mayhem on each other and AI enemies. However, in those games, you are doing the same thing over and over again, shooting enemies. In this game, I am investigating an area and interacting with the world, so I don't need as many places if I do more in the ones that I need to.
Having more houses to loot just means I have more loot. More dungeons just means more Hack and Slash or Run and Shoot. There are other games for that if I want to do that. I do agree that more attention to detail could have been lavished and more buildings could have a purpose. However, I am getting overwhelmed by what is in my quest list and I am only a third of the way through the MQ. Just tonight, I looked at the strategy guide for the first time to see which quests I could get through quickly and realized most of the ones I have are going to take me several nights for each one to get through. So, I have enough to do without having to poke my way around random buildings.
Sure, there are no large towns, but there are no large towns just outside of Vegas. That is a fact. So, what towns are they supposed to add? Could the towns they do have be a little bigger? Sure, but I am getting tired right now of all the walking I am doing for a certain arms merchant as the choice of Fast Travel marker locations leaves a bit to be desired. I think it is big enough map for the game in that regard. The buildings in the towns that you do go into that you can enter do serve a purpose for the NPCs that live in those towns. So, I would expect the other buildings to be bordered up if they are vacant.
Yes, medium sized buildings set off by themselves could have been another Dunwhich or Tenpenny or Robot Factory or something else. I wade through a nest of those annoying cazadors to get to building I could not go into. That makes me go grrrr and then I save and unload most of my ammo into the building. Then I reload, but I digress.
However, while the map may be lacking in things to do, I do agree on that, game is not lacking in things to do. I do think the map serves the game just fine. I can see this far in that I have at least 6 play throughs on the MQ and I am trying to ignore the side quests that keep getting thrown at me, and I have not explored the companion quests and I have not started the completion quests (those ones where you collect everything of a certain type like snowglobes) and I have done the total Freelance playthrough either. And, this is on the map we have.
